The reasons for the collapse of storage shelves, how to avoid such accidents?
Stimulated by the rapid development of the e-commerce industry, the demand for the use of shelves in various industries has also increased. This has led to the production process and production materials of the shelf manufacturers in the market competition environment that did not meet the specifications, and the products were produced. Racks will have problems in quality, load-bearing, rust prevention and other aspects.
How to prevent and avoid shelf collapse accidents caused by the purchase of inferior shelves has become the most concerned issue in warehouse procurement shelves in various industries. Let us analyze the reasons for shelf collapse and how to avoid them.
一、 The shelf is impacted by external force, mostly by forklift. When the warehouse shelf is impacted by excessive external force (mostly due to misoperation of the forklift), the structure will be damaged or squeeze load, which will cause collapse or burying. The hidden danger of the collapse of the shelf. So what standard measures should we take to reduce the possibility of collapse?
1. Establish a sufficiently wide aisle space. Although maximum space utilization is the key goal of every warehouse, warehouse safety is still the top priority. Many companies use forklifts to provide the "minimum" aisle when setting up shelf aisles. The lowest limit is very likely to be too narrow, especially for inexperienced drivers to operate, it will cause impact on the shelf. Therefore, a sufficiently wide passage can not only ensure safe production, but also increase productivity.
2. Install anti-collision corners and anti-collision guardrails on the shelves. This is a cheap and simple way to protect the shelves. The shelves listed on the turning corners have a great chance of being hit by the forklift. Therefore, any type of foot guard can well prevent the shelves from being damaged by the forklift.
3. Regulate the use of forklifts, and place restricted signs in the warehouse, such as speed limit, load-bearing, etc. The driving speed of the forklift does not exceed 8km/h, and the speed near pedestrians does not exceed 5km/h. Low-speed operation is also suitable for the area of the pallet rack. In the aisle, near the corner or in the rack tunnel should be the "slow walking" area of the forklift.
二.、The shelf exceeds the load. When using the shelf, it must be strictly controlled within the load-bearing range of the shelf, and the load must not be exceeded. Under normal circumstances, the beams are not damaged and are equipped with safety pins. When a stable pallet is installed on them, it is still necessary to pay attention to the load of the beams also need to be evenly distributed.The load-bearing capacity of the beam also depends on the evenly distributed load, and if a decorative board is used instead of laying the tray flat on the beam, it will also change. At this time, a damaged pallet or a high-density load can be used to compromise the loading of the beam.Poor shelf design. According to the size, weight and density, the approximate load-bearing range of the shelf is usually determined during the design. Therefore, incorrect design may cause the shelf to collapse during use.
三、Poor shelf design. According to the size, weight and density, the approximate load-bearing range of the shelf is usually determined during the design. Therefore, incorrect design may cause the shelf to collapse during use.
When designing the rack structure, factors such as actual use, equipment conditions, load properties, material supply and installation conditions should be comprehensively considered, and the form of the structure, overall structure and manufacturing materials should be selected reasonably, and the technology should be advanced, economical and reasonable, safe and applicable, and quality Guarantee.
